A refined structural model of composite aircraft wings for the enhancement of vibrational and aeroelastic response characteristics
Abstract
This paper presents an analytical study of the vibrational and static aeroelastic response of anisotropic composite aircraft wings modeled as thin-walled beams. To this end, a response beam model incorporating a number of important effects essential for a reliable prediction of wing response characteristics is developed. The implications of the bending-twist structural coupling induced by the ply-angle distribution are examined and the power of the tailoring technique toward enhancing the dynamic and static structural characteristics is revealed.
